Q184 / 200 · NEET 2022 (Phase 1) · Zoology

Natural selection where more individuals acquire specific character value other than the mean character value, leads to:

  • Correct answer
    A
    Directional change
  • B
    Disruptive change
  • C
    Random change
  • D
    Stabilising change

Solution

If the organisms/individuals at one extreme of the distribution contribute more offspring to the next generation than other individuals do, then the mean of the population will change. This changes the normal distribution into one tailed-distribution. This is the case of directional selection. If directional selectional operates for many generations, an evolutionary trend within the population results.

Hence, the correct answer is option: 'A'.
